With push notification, this is really cool. I like the caravan/public trip idea (you keep track of where everybody else is in a group ride), but I haven't tested it yet.
Trapster is a social networking mobile application and website, provided for free, that maps out and alerts users in real time to the presence of live police speed traps, red light cameras, speed cameras, and areas where police often hide. In addition, it allows users to record trip data and share it via the web, including interfaces with Facebook and Twitter. Trapster was recognized by Time Magazine as one the 10 Best iPhone Apps for Dads in June 2009, and as one of the 20 Sexist Apps for Men by iSmashPhone.com in July 2009. In addition, Wired listed Trapster as the number 1 application in their 10 Mobile Applications that Make the Most of Location and CNET named Trapster as their number 1 free iPhone automotive app.
Pete Tenereillo launched Trapster, the modern equivalent of flashing your headlights to warn other motorists of police speed traps, in November 2007, and by early 2009 had 1/2 a million users signed up. On July 20, 2009, Trapster had signed up its 1 millionth user. Less than a year later, the company claimed to have in excess of 4 million users.
Trapster can use Wi-Fi or GPS to pinpoint the user's current location phones with GPS. and send them audio alerts or text messages when they are approaching a ticket threat. Users report the existence of a trap by pressing the touch screen or using a key combination on the mobile device. To negate the effect of pranksters or the police entering bogus locations, users can verify the locations of existing traps in the same manner.
Trapster gives greater weight to traps that are rated more reliably. Users
can customize the alerts via the Trapster website or the mobile app so that they only receive notifications of conditions they are interested in, such as red light cameras or live police.
Information about static traps, such as red light cameras and speed cameras, stays in Trapster's database indefinitely. Live speed trap locations are kept in the system for one hour, as it is likely that the officers will move on to a new location.
